Thanks, Hans, Again...
I don't use KDE, but noblank supports it. I wasn't about to install KDE to test a tiny script, so I did my tests on a machine at work. Somehow when I merged in KDE support, I got rid of the sleep 60 turning the loop into a busy wait. Once again, we have Hans Fugal to thank for correcting my carelessness. I've quietly fixed my previous post. Let's just keep this our little secret.
